Daily activity schedule, gregariousness, and defensive behaviour in the Neotropical harvestman Goniosoma longipes (Opiliones: Gonyleptidae)
In this paper we provide a field account of some aspects of the behavioural biology of Goniosoma longipes (Roewer), a harvestman which commonly occurs in caves in South-east Brazil. During daytime,… Expand
Parental investment and the evolution of subsocial behaviour in harvestmen (Arachnida Opiliones)
The diversity of reproductive strategies within the arachnids rivals all other arthropod groups. However, with the possible exception of spiders and scorpions, evolutionary biologists have overlooked… Expand
Seasonal Patterns in Activity Rhythm and Foraging Ecology in the Neotropical Forest-Dwelling Ant, Odontomachus chelifer (Formicidae: Ponerinae)
ABSTRACT We provide qualitative and quantitative data on the natural history and foraging behavior of the ground-dwelling ant Odontomachus chelifer (Latreille) (Formicidae: Ponerinae) in a forest… Expand

BACKGROUND AND AIMS Functional groups of species interact and coevolve in space and time, forming complex networks of interacting species. A long-term study of temporal variation of an ant-plant… Expand
Assemblages of endophagous insects on Asteraceae in São Paulo cerrados.
A survey of the endophagous insects fauna associated to Asteraceae capitula was carried out from 2000 to 2002 in eight cerrado sensu stricto sites located in the Brazilian state of Sdo Paulo.… Expand
Daily activity of ants associated with the extrafloral nectaries of Turnera ulmifolia L. (Turneraceae) in a suburban area in Southeast Brazil.
The ant fauna visiting the extrafloral nectaries (EFNs) of Ihe weed Turnera, ulmifolia L. (Tumeraceae) was monitored day and night in a suburban area in Southeast Brazil. The ant densilY and number… Expand

Adaptive speciation can occur when a population undergoes assortative mating and disruptive selection caused by frequency-dependent intraspecific competition. However, other interactions, such as… Expand
Nestedness across biological scales
Biological networks pervade nature. They describe systems throughout all levels of biological organization, from molecules regulating metabolism to species interactions that shape ecosystem dynamics.… Expand
